"Sorry Not Sorry" marks Demi's third annual summertime banger. ("Cool for the Summer" and "Body Say" came out in July 2015 and 2016, respectively.) July may be halfway over, but given how wild this party looks, "Sorry Not Sorry" could still be a serious contender for Song of the Summer. Anything could happen before Labor Day weekend.
